Question

65-4^x+2=1000000⁰

Answer 1

65 - 4^{x + 2} = 1000000⁰

=> 65 - 4^{x + 2} = 1

=> 4^{x + 2} = 64

=> 4^{x + 2} = 4³

=> x + 2 = 3

=> x = 1

vậy_

Answer 2

\(65-4^{x-2}=1000000^0\)

\(65-4^{x-2}=1\)

\(4^{x-2}=65-1\)

\(4^{x-2}=64\)

\(4^{x-2}=4^3\)

\(x-2=3\)

\(x=3+2\)

\(x=5\)

Vậy x = 5

=))

Answer 3

\(65-4^{x+2}=1000000^0\)

\(65-4^{x+2}=1\)

\(4^{x+2}=65-1=64\)

\(\Rightarrow4^{x+2}=4^4\Rightarrow x+2=4\)

\(\Rightarrow x=4-2=2\)

Vậy \(x=2\)

Answer 4

\(65-4^{x-2}=1\)

\(4^{x-2}=64\)

\(4^{x+2}=4^3\)

\(\Rightarrow4=4\)

\(\Rightarrow x+2=3\)

\(x=1\)
